Better way to load data to table

Hi;

I have a table that has four fields as float8[]. I have a serial new data
for each array. Each time I have new data I have to update more than 6000
rows for all four field. But using "update (ta ble)" to load in the new
data is just too slow. Does anybody know a more efficient way to update
large data set in an array?

Thanks for help.
